After updating my iPhone 4S with ios6, it seems I have lost over half the Applications from the Home Screen, including Settings, Safari, Camera, Photos and more plus all the original downloaded Applications. Can anyone help please?
The built in apps can't be deleted. If you want them reset back to their original arrangement on your screen, go to Settings>General>Reset>Reset Home Screen Layout. If your purchased apps are missing, either sync them back to your phone with iTunes or redownload them for free (see http://support.apple.com/kb/HT2519).
